Our precision cut metal mounting base provides a rock solid foundation for your devices and is designed to have an OEM-like fit in your truck's dash.


IMPORTANT FITMENT NOTE: Our dash mount is only compatible with models equipped with a recessed dash tray. A mid-year refresh was done in 2022. See image below.


If you have the upgraded 13.4 inch infotainment touch-screen, we're working on a mount specific for your truck. Sign up here to get updated when we launch.

What's included in the kit?

  • x1 Dual Ball Mounting Base
  • x1 standard 7cm Carbon Fiber + Kevlar hybrid mounting arm
  • x1 device holder (choose between our Universal, XL Universal or DiabloM6 Magnetic Phone Mount)

Note: For kits containing 2 device holders (2 phone holders, phone holder + tablet holder), 2 Carbon Fiber + Kevlar Mounting Arms are included.

Due to the presence of kevlar, the mounting arm has a subtle blue hue in direct light.

Base-Only Option

You may opt for just the Dual Ball Base and customize from there (no mounting arms or device holders are included with the base only option).

Our base comes with 2 integrated 20mm mounting balls that work with any of our device holders and mounting arms.

There is also a 3rd mounting location concealed within the Bulletpoint logo that is AMPS compatible which means you can mount up to 3 devices in total.

We sell AMPS Mounting Balls separately but you may also choose to secure a 3rd party AMPS-compatible mount as well.

In addition, the Platform Base features an integrated camera-ready 1/4"-20 threaded insert so you can mount your camera using a 1/4"-20 adaptor (not included).

    A rock solid mounting system starts with a rigid mounting base.

    Our Metal Series bases are made from precision laser cut metal which results in a solid foundation for mounting your devices.

    All hardware is included for a straightforward installation that is extremely sturdy.

    2 possible installation options are available and depend on your vehicle's dash.

    1. Rubber Well Nuts (Heavy Duty - no panel removal necessary)
    2. Nuts & Bolts (Heavy Duty - panel removal required)

    Note: Requires removal and drilling the dash panel (4 holes). Includes all necessary hardware for an easy installation.

    Buy with confidence knowing that you're backed by our Limited Lifetime Warranty.

    Our DiabloM6 magnetic phone mount requires a thin metal plate affixed to the back of your phone. Please note that this also prevents Wireless Charging. The DiabloM6 is not directly compatible with MagSafe equipped iPhones. 

    The metal plate may not stick to all phone cases. For example, many silicone cases have non-stick properties that may not work with the metal plate.

    Garmin RV890

    The ball size for the RV890 back plate is 21.83 mm. Purchased the Chevy mount, 10cm long mount arm, "drop down" kit with connector, and the 20mm to 22.4mm connector. Perfect setup. Exactly why I purchased this product. The Garmin RV890 is within reach of both the driver and the passenger. In the photo, the third 20mm ball, is the 1/4" -20 camera adapter. Screws into this mount. Future GoPro mount point.

    Pretty nice

    The arms are very cool. The carbon fiber looks awesome. I do wish the mounting ball clamps were a bit more adjustable. Like going from portrait to landscape on my phone requires me to loosen the wing nut

    Good product.

    Good product. Probably could have used the larger phone mount. It is a bit hard to install with one hand.

    Works Great

    I love the mount. Hits great and holds my phone’s perfectly. What’s neat is that I can add a suction cup mount if I needed an extra device. Installation was easy and took about 30 minutes.
